High density shadow of pulmonary nodules is a description of pulmonary imaging, which usually refers to part of pulmonary nodules. Pulmonary nodules are opaque high-density shadows located in lung parenchyma, with a diameter less than 3cm. It is called a nodule. This kind of pulmonary nodule is common in single or multiple cases.

Nodules can be divided into solid nodules or pulmonary solid nodules, and pulmonary solid nodules can be divided into partial solid nodules or ground glass nodules. Pulmonary nodules generally refer to nodules smaller than10 mm. Not all pulmonary nodules will develop into lung cancer, most of which are benign lesions, but some of them are relatively early tumors or precancerous lesions. Of course, patients can be treated with integrated traditional Chinese and western medicine during the treatment. The combination of traditional Chinese and western medicine can alleviate the condition and improve the symptoms. In daily life, patients should pay attention to adjusting their own life rhythm and law, go to bed early and get up early, don't stay up late, and pay more attention to rest. Diet should be based on light and digestible food. You can eat more fresh fruits or vegetables and eat more foods with high nutritional value to supplement the nutrition that patients lack.

Pulmonary nodules are basically divided into two types, benign nodules and malignant nodules. The former includes some benign tumors or tuberculosis, sarcoidosis, inflammatory pseudotumor or inflammatory nodules, or primary malignant tumors and metastatic tumors. If your lung nodule density is very small, there are no obvious clinical symptoms. It is recommended to follow up this situation. The reason for the increase of lung nodule density may be benign or malignant. Benign lesions are common in nodular granuloma and tuberculoma. Malignant lesions can be primary lung cancer and metastatic lung cancer.

Nodular granuloma is a non-necrotizing epithelioid granuloma with unknown etiology. Nodules are composed of macrophages, epithelioid cells and lymphocytes. The components of granuloma lead to high-density CT images. Tuberculoma is a stable lesion in pulmonary tuberculosis. The center of the nodule is caseous necrosis and calcification, so the density on CT increases. Lung tumors often show a single ground glass nodule shadow. Because the tumor tissue is a solid mass composed of tumor cells with rich blood flow, it also shows high density on CT. Both primary lung cancer and metastatic lung cancer can show nodular high density shadow. Nodular high-density shadow was found in physical examination, so it is recommended to seek medical advice and improve relevant examination to check whether it is a lung tumor.
